using a satin stitch is a great idea. it sounds like extra work, though, and i'm sure that's not your intention! the more stitches you have [per inch] would be more noticeable and it may look a bit off kilter when you would sew a long length that way. you would be drawing more attention to those areas, & that's NOT what you want. I agree with others that after it is quilted you will barely notice it. can't wait to see it quilted. i'm glad you showed the closeup--i'm considering doing one of those, and it's interesting to see how the florals show thru on a light background.
